The quantikine Goat Growth Hormone Releasing Peptide (GHRP) immunoassay is a 4.5 hour solid phase elisa designed to measure Goat Growth Hormone Releasing Peptide (GHRP) levels in cell culture supernates, serum, and plasma. It contains e. Coli-expressed recombinantGoat Growth Hormone Releasing Peptide (GHRP) and antibodies raised against recombinant Goat Growth Hormone Releasing Peptide (GHRP). This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural Goat Growth Hormone Releasing Peptide (GHRP) showed dose response curves that were parallel to the standard curves obtained using the recombinant quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural Goat Growth Hormone Releasing Peptide (GHRP)
